Abstarct: The current situation of electric energy storage in the global energy storage field in recent years and the application scale of electric energy storage in the existing energy storage system are introduced. According to the analysis of the mature electrochemical energy storage battery at present, the characteristics of zinc-nickel batteries are emphatically analyzed. Firstly, the low-temperature discharge performance, life and high current charge-discharge performance of zinc-nickel batteries are described. The results of charge-discharge experiments of simulated energy storage system show that zinc-nickel batteries have the characteristics of long cycle life and high charge-discharge efficiency. Secondly, the working principle of single-fluid zinc-nickel batteries is introduced. The current pilot-scale products of single-fluid zinc-nickel batteries and 50 kW·h energy storage system are summarized and discussed. The analysis shows that as a new type of battery, zinc-nickel batteries have long cycle life, good safety performance, low manufacturing and maintenance costs. With the development of new materials in recent years, manganese cathode successful experiments on zinc-based batteries have promoted the research and development of zinc-based batteries such as zinc-air batteries and zinc-iron batteries. In the future, zinc-nickel batteries will be brilliant in the energy storage market.%本文介绍了近几年电力储能在全球储能领域的现况及电力储能在现有储能系统中的应用规模.针对目前较成熟的电化学储能电池进行了分析, 着重分析了锌镍电池的特点, 首先对锌镍电池的低温放电性能、寿命、大电流充放等性能进行了阐述, 模拟储能系统充放电实验的结果表明锌镍电池具有循环寿命长和充放电效率高等特点.其次对单液流锌镍电池的工作原理进行了介绍, 就目前单液流锌镍电池的各个型号的中试产品以及50 kW·h储能系统进行了总结和讨论, 分析表明锌镍电池作为一种新型的蓄电池, 其循环寿命长、安全性能好、制造和维护成本较低, 随着近几年新材料的发展, 锰正极的锌基电池实验成功, 促进了锌空气电池、锌铁电池等系列锌基电池的研发, 锌镍电池未来在储能市场将会大放异彩.
